I'm Going To Try Experimenting With Porcelain, But Not Sure Where To Start

As a professional hobo, I have limited access to vehicles and it seems that ceramic and clay suppliers are scarce in my area, so I have to do a lot of buying online and have it shipped. I want to try out working with porcelain, but I can't go to a clay supplier and ask questions and then buy accordingly. I've read a little about it online, I think the standard variety of porcelain clay should give me the results I'm looking for. I just can not find anywhere to buy it from.

Any of the clay companies will ship it to you, but it's expensive to ship. The shipping may cost more than the clay if you just get one or two boxes. I use porcelain from Standard Ceramic. The cone 6 #365 and cone 10 #257 are both wonderful clay bodies. I also recommend Helios from Highwater and Babu from Laguna.
